Improvement in running-gears



iuurT-EDSTATES PATENT OFFICE GEORGE w.v GILMOEE, 0F' WEATEEREOED, TExAs, AssrGNoE To HIMsELE AND E. M. DAvIs, 0F sAME PLAGE.

Specification forming part of Letters Patent No. 172,992, dated February 1, 187,6; application led l October 8, 1875.

To all whom it may concern:

Beit known that I, GEORGE W. GILMORE,

of Weatherford, in the county of Parker and State of Texas, have invented a new and Improved Vehicle, of which the following is a specification: A

In the accompanying drawing, Figure 1 represents a vertical longitudinal section of myy improved vehicle on the line c c, Fig. 2;

Fig. 2a top view, with body detached to show suspension-frame, and Fig. 3 a rear elevation of the same.

Similar letters of reference indicate correspondin g parts. l

The invention relates to au improvement in suspension-vehicles, and upon the patent granted to James Patterson, April 16, 1850.

The invention consists mainly in improvements in lthe connections oi' the axles with the springs, perch, and other parts, as will'be fully described and pointed out by the'claims.

' vIn the drawing, A A represent the front and hind axles of my vehicle suspension frame,

which are made of oval-shaped iron, as this shape gives it greater strength, and is less liable to spring without anyincrease of weight over the old round irons. The axles are made of upper and lower bars, which are braced in suitable manner and joined near the outer axle ends by square or angular connecting -pieces a, which form shoulders, to which the side stays b of the perch may be bolted without weakening any parts, dispensing with the collar or other attachments to the axle ends, that are soon worn outthereby.

The angular "shoulders of the front axle have to be madevstronger and heavierl than thos e/ot\the hind axles, as the front axle has no-/connecting-stays,and is more exposed to vspring forward and back.

attached to the axles by means of clips e,

that are passed through eyes of the upper axle-bar and secured by screw-nuts thereto. This requires no weakening of the springs,

.as it secures the same without bolt-holes, that detract from their strength.

The side stays b extend from the shoulder of the axle to the middle of vthe perch D, but are not attached directly to the same, but to a stay-post or upright, f, bolted to the main perch, and a strengthening-brace, D', that imparts to all the parts additional strength.

The perch D and suspension-brace' D aremade ot'oval steelbars, the latter being curved as required, and bolted, together with the upper stay d ot' the rear axle,- to the. rear part of the main perch. v

The front part of brace D is bent up toward the -perch "and the fifth-wheel E, forming a n bearing for the same, and curving them down to the lower axle part to be bolted to the centerpost of the same. rlhe front of brace d of the perch passes 'over the top of the fifthwheel to the top of the king-bolt, forming a washer for the fifth-wheel and establishing a corresponding strengthening-.connection to that at the rear end of the perch.

The fifth-wheel E extends in front of the axle, the lower bearing being curved back to 1 the sidesof the same, to form additional stays to the projecting front ends of the fifth-wheel. The connection of the supporting-springs with the axles, and the rigid connection of both front and hind axles by the brace', produce an iron suspension-frame of great strength and durability, applicable to allkinds of vehicles, and of specialadvantage in the southern sections of the country, in which the use of wood to wagons, &c., is to be avoided.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. A rear axle, consisting ot' two opposite -arch bars connected at each end by angular pieces a, as and for the purpose described.

` 2. The combination, with rear axle and reaches, of a middle post, B, that braces axle and secures the reaches to it, as shownand described.v

3. A rear axle, provided with eyelets, clips,

and'mddie post, to secure the spring, as

6. A reach provided with upper part of fifth-wheel, in one piece therewith, fastened at top of front axle," and connected by kingbolt and brace with front spring, as described.

G. W. GILMORE.
